Doonesbury by Garry Trudeau for October 18, 1986
Transcript:
Honey: Sir, I know you're probably thinking I've acted disloyally in turning you in to the authorities. But try to understand. You hadn't completed a sentence in four months. I did it out of desperation! I missed you, sir. I missed the grateful, spirited man who first walked into my life ten years ago. So I took matters into my own hands. In time, I think you'll thank me for... Duke: I've paid a large Mexican $50 to kill you.
What’s ironic is that Honey is blaming the wrong substances. Duke was already heavily into drugs when they met. What’s been wrong with him recently in this story was the zombification.
